Hand-picked by BloomLED among the most reliable temperature controllers on the market, the CornWall Electronics reversible thermostat 220V gives you full command over the temperature inside your grow tent. One single plug, two duties: drive your heater in winter or your extractor in summer — and never let your plants drift outside their ideal range.

One socket, two jobs: trigger your heater when temperature drops, or kick in your extractor when it rises. A versatile controller that adapts to every season, from veg to flower.
Read measured temperature and your setpoint at a glance. Simple button-driven settings, no convoluted menus: a thermostat built for growers who want results, not configuration headaches.
If the mains drops, your settings are kept by the internal cell. When power returns, the thermostat resumes the same cycle automatically — no intervention needed.
The thermostat works with most domestic 220-230V extractors, within the rated power of the plug. For low-consumption EC fans or extractors with dedicated PWM control, check compatibility with the manufacturer: a built-in variable speed driver can interfere with the simple ON/OFF action of the thermostat.
What is the difference between heating and venting modes?In heating mode, the socket switches on when temperature falls below your setpoint. In venting mode, it switches on when temperature rises above the setpoint. The reversible CornWall Electronics design lets you pick the right behaviour: one device to manage your grow room year-round.
Smart pairing: combine this thermostat with a remote temperature probe or an air humidifier for a fully managed grow tent climate.
